Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems like she has cold along with
sinus infection and it seems to be a viral infection leading to cold and phlegm,cough, congestion, headache and blotchy tongue is due to inflammation of tongue causing
GLOSSITIS and it is also occurring secondary to infection and inflammation..
As she has already finished antibiotic course Z-Pak now she should continue taking decongestant like
Phenylephrine, if there is excess of phlegm she can take mucolytics like Bromohexine, take Ibuprofen or Tylenol for headache and body pains, do warm saline gargles and steam inhalation..
For cough she can take cough expectorant containing
Guaifenesin..
Avoid spicy and chilled foods, drink plenty of warm fluids and take ample of rest..
For blotchy tongue she can gargle with a numbing mouthwash if there is pain and burning, take
Multivitamin supplements and take a soft low spiced diet..
Hope this information helps..
Thanks and regards..
Dr. Honey Nandwani Arora.
